What does it mean to ride hard then pull out wet?

Answer 1

The expression is "ridden hard and put away wet". It originally referred to horses. Back in the day if you raced your horse 'hard' the horse would sweat, after putting it away in the stable. Usually this meant that the horse as well as the rider were thoroughly exhausted from the 'ride'. In modern times this expression has been used to describe vigorous sexual encounters; where usually the phrase is used to describe how you left your partner feeling "ridden hard and put away wet".
